[Elecraft] Let me build your K2.
I have built 90 K2's to date, and many of the other Elecraft kits. Let me build your radio. My rates are reasonable and you get a built radio ready to play. 73 Alan W1HYV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 Aux Digital Mode Connection Box
Hi Lynne, I know that many ops are running commercial boxes such as the Rigblaster, the Buxcomm interfaces, Tigertronics, and the MFJ interface. For myself, I run the orignal Rigmaster with RJ45 connectors (i.e., I originally used it with an ICOM 706MIIG) on PSK31 and RTTY with my K2. To use the Rigblaster, set the jumpers to the Kenwood radio configuration. I would buy an M-8 Rigblaster (i.e., for Kenwood) instead of the RJ45 connector variant because the cabling will be more straight forward. 73, Les WA3SGZ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Preamp, Attenuator on K2 #4901
Hello, All. I just finished K2 #4901 and it works great. The only thing I have a question on is the preamp setting. When the annunciator is on over the preamp, it seems as though background noise goes down and the signal strength is reduced. In fact, there seems to be little difference between the preamp and att settings. I've been through the schematic and carefully reviewed the parts installed for the preamp and I can't see anything wrong. Has anyone experienced this problem, if it is one? 73 and thanks.

[Elecraft] kx1 #1056 atu
Okay! I found the problem. I had reversed leads #1 #3 on T1. After correcting this power out in TUNE shown as P3.0 and the DL1 read 7.06 v which is where it should be, and SWR = r1.0. I hooked up a 30m antenna and got an SWR of r4.5. Man you could hear the relay chatter. I even got a NULL on C9 of 1.5mv on my DDM's 200mv scale Tnx for the help de rc kc5wa -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

RE: [Elecraft] Preamp, Attenuator on K2 #4901
Jim, Other than a faulty solder connection or an incorrect resistor value (R74, R75, R76, R77), I can think of only 2 things that might cause the PreAmp to not work - T6 could be connected incorrectly or the windings shorted together, or C146 may be faulty. Try tacking a 0.01 uF capacitor across R77 (bottom of the board) as a check for an open C146 and if that doesn't fix things, try rewinding T6. 73, Don W3FPR -Original Message- I just finished K2 #4901 and it works great.

The KX1 build time was much less than the other Elecraft rigs that I've built. It's a sweet little rig. It does about 3W output with a 12V 1A regulated power supply. I'm going to get used to it for a bit, after which I'll build and install the 30m module and the internal ATU. This would be a nice Elecraft starter rig for someone to build. Great job Elecraft!

Pomona Electronics makes a binding post, standard, double banana (female) to BNC male, part number Pomona 1296 that I use and it's great.

[Elecraft] Binding Post Failure (WAS: KX1 s/n 1005 lives!)
Many banana plugs and jacks use nylon insulation which is a *terrible* RF insulator. Nylon is hygroscopic (absorbs moisture) so its insulating properties are highly dependent upon the relative humidity. Running 15 watts into an end-fed wire I literally melted a banana jack that looks just like those shown at the top of the page here: http://www.oselectronics.com/ose_p111.htm In just a few seconds of sending, I smelled hot plastic and saw smoke rising as the insulation sagged. As it happened, I had a voltage loop (point of high RF voltage) at the rig on that band and it caused a quick and total failure. But even at voltages below that which caused failure, part of the RF was being converted into heat instead of electromagnetic waves. All of the Pomona hardware that I've seen uses polycarbonate insulation. This is superior, tough stuff! Pomona makes these adapters for use with test equipment at very low voltage levels. The popular 1296 that Matt, K7OE mentioned, is rated to 500 vac max (see data sheet at http://tinyurl.com/7mca5). They don't publish dielectric info or mention their losses at RF, but that sounds adequate for RF power levels up to some tens of watts into a high impedance (1,000-ohm) load. Of course lower impedances mean lower voltages. I still use nylon banana plugs and jacks for single wire and open wire feeder connections, even at QRO power levels, but I never rely on the nylon for insulation. The jacks are always mounted in an acrylic or polycarbonate insulating panel with ample spaces between them.
